SWIFT FOR WINDING-MACHINES.

Specification of Letters Patent.

Patented Nov. 11, 1919.

Application filed December 16, 1918. Serial No. 266,957.

To all whom it may concern:

Be it known that I, WVILLIAM C. KEY- WORTH, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Swifts for VVinding-Machines, of which the following is a specification.

This invention relates to swifts for winding machines. These are usually constructed with pairs of spokes in which the members of each pair are connected by cords which support the skeins. These cords slip radially inward on the spokes when the swift is in use, in consequence of which the attendant is kept constantly busy moving them back to keep the skein taut and also to true it up centrally of the swift, because if it is not thus true the swift is unbalanced in rotating and produces an undesirable intermittent resistance to the draft of the thread. My object is to provide a swiftwith spokes outwardly held by springs so as to keep the skein under tension and also trued with reference to the aXis of theswift from start to finish of the unwinding thereof from the swift, and to form such swift so that it shall be substantial and durable in construction and light in weight, and so that the manufacturing cost may be kept as low as possible, particularly (according to one form of my invention) by making the spokes separable from the center part of the swift so that to provide swifts of different diameters it will only be necessary to make-the spokes in different sizes and fit them to center parts all constructed of the same size.

In the accompanying drawings,

Figure 1 is a side elevation of one form of my invention;

Fig. 2 is an elevation of said form viewing the same at right angles to its axis;

Fig. 3 is a view similar to Fig. 2, but enlarged and showing certain parts in section;

Fig. 4 is an elevation of a fragment of the hub;

Fig. 5 is an elevatiompartly in section, of one of the spokes;

Fig. 6 is a perspective view of one of the sockets attached to the hub;

Fig. 7 is a sectional View on line 77, Fig. 3;

Fig. 8 is an elevation of another form of the swift viewing the same at right angles to its axis, certain parts appearing in section; and

Fig. 9 is a side elevation of such other form, partly in section.

In both forms of the invention there is a center part comprising a hub a, which is provided with suitable axial bearing portions 6 and with several radial holes 0 bored at equidistant points in the hub, and tubular sockets (Z which project radially from the hub and have their inner ends received by and preferably glued in the holes 0. For a purpose to be explained each socket has longitudinal diametrically opposite slots 0 extending partway the length thereof from its inner end and beyond the hub, and the hub is made to prevent collapse or contraction of the slotted inner end of the socket, due to the slots, by countersinking a groove 7 in the bottom of the hole of the same cross-sectional shape and size as the hole, such groove receiving said inner end of the socket.

In the sockets are arranged spiral springs g.

In both forms there are further a series of skein-supporting spokes arranged and movable radially in the respective guiding means therefor which the sockets constitute, their outward movement being limited by the sockets. In both forms each spoke in the adaptation illustrated consists of astraight shank 7L having at its outer end a transverse suitably shaped skein-supporting blade 2' secured thereto, as by slitting the outer end of the shank and setting the blade in the slit and fastening it with a pin j. In both forms, further, each spoke has means to limit its outward movement in its socket.

In Figs. 1 to 7 said means last referred to consists of a cotter pin is which penetrates the slots 6 of the socket and is kept in place by the washers Z bearing against the slotted opposite sides of the latter, and the stem h of the spoke has a longitudinal slit m in its inner end formed enlarged, as at n in Fig. 5, for the normal reception of the cotter pin. The slit m is narrower than the cotter pin is thick so that the stem cannot move relatively to the cotter pin unless sufficient force is exerted longitudinally of the spoke to cause the cotter pin to spread the slitted portion of stem h, as by an outward pull on the spoke when the cotter pin abuts the outer end of the slots 0. The slipgrip' connection thus afforded between the pin 7': and the stem it permits the stem and its blade 2' to be removed in case of damage thereto, and. the parts 70 and h'i giving the spoke member a two-part character; the

construction also permits the center parts of the length to be designed to produce swifts of any selected diameter to be readily attached to the center parts as called for.

In Figs. 8 and 9 the means to limit thev outward movement of each spoke in its socket consists of a pin 0 driven through the stem h and projecting at its ends into the slots 6.

In either form of the invention the pin 70 or 0 obviously prevents rotation of the spoke, so that the blade 11 remains coincident with the plane of the axis of the swift.

In both forms of the invention the inner end of each stem h is preferably reduced to form a shoulder at p against which the corresponding spring 9, which abuts against the hub in the hole 0, bears, holding the stem to the outward limit afforded by engagement of its pin it or 0 against the outer ends of the slots 6. In both forms of the invention, further, the stems are adapted to abut directly against the hub; if the slots 03 were closed at their inner ends to afford abutments for the pins 73 or 0 the shock incident to the pins engaging such abutments, as on the swift being allowed to fall on the floor, would damage or Weaken the swift where the direct contact of the spokes with the hub would not do so. 7

The hub and stems it may be made of Wood; for the'purpose of combining lightness with strength the sockets are preferably .composed'of fiber. I

Having thus fully described my inven-,

tion, what I claim a new and desire to secure by Letters Patent is 1. The combination of a center part including ahub having radial holes formed therein and tubular radial sockets each having one end portion longitudinally slotted and fitted into one of the holes,the center Copies of this patent may be obtained for part having within said end of each socket means to hold the said end against contraction, and skein-supporting spokes radially movably arranged in said sockets and engaged in the slots thereof.

2. The combination of a center part including a hub having radial holes formed therein and tubularradial sockets each having one end portion longitudinally slotted and fitted into one of the holes, the center part having at the bottom of each hole a groove conforming with the cross-sectional shape and size of the corresponding socket and receiving and holding against contraction the slotted end of said socket, and skeinsupporting spoke radially movably arranged in said sockets and engaged in the slots thereof.

3. The combination of a center part having radial sockets, radial and radially movable skein-supporting two-part members, one part of each member having limited radial movement in the socket and the other part including a shank extending into the socket and radially, outwardly detachable from the first part.

4. The combination of a center part having radial sockets, radial and radially movable skein-supporting two-part members, one part of each member having limited radial movement in the socket and the other part being outwardly detachable from the first part and having a slip-grip connection therewith.

5. The combination of a center part having radial sockets, radial and radially movable skein-supportin two-part members, .one part of each mem er having limited radial movement in the socket and the other part being outwardly detachable from the first part and havinga radial slit receiving and forming a slip-grip connection with the first-named part.

In testimony whereof I affix my si -nature.

WILLIAM G. KEYWOItTH.
